K, L, M, and DWV are grades of copper tubing commonly used in plumbing applications. Type K is the thickest and most durable, often used for underground and water supply lines. Type L is slightly thinner and suitable for both above-ground and underground plumbing. Type M is even thinner and commonly used for residential plumbing, such as water lines and refrigeration. DWV (Drainage, Waste, and Vent) is a thinner grade specifically designed for drainage and venting systems.
